shmat on tilepro
System V shared memory operations
sys_shmat(int shmid, char *shmaddr, int shmflg)| number | 196 (0xc4) |
|---|---|
| abi | common |
| kconfig | CONFIG_SYSVIPC |
| family | sysvipc see the whole family on tilepro |
| entry point | sys_shmat |

Registers
| register | value |
|---|---|
r10 | 196, the syscall number |
r0 | int shmid |
r1 | char *shmaddr |
r2 | int shmflg |
r0 | the return value |
Then run swint1 to enter the kernel.
The kernel uses r1 to signal an error for ordinary calls.
Fast atomic calls use negative numbers and have different register behavior.
This architecture was removed from the Linux kernel in Linux 4.17. The newest release with a syscall table here is Linux 4.16. The other removed architectures live on the historical architectures page.
